- Recurring budget entries can now use an interval (monthly, half-yearly, yearly) and optional virtual budgeting (#240). With virtual budgeting on, a large infrequent bill is smoothed evenly across the months — e.g. a 1,200/year insurance shows as 100/month in the monthly summary, balance and CSV export instead of a single lump in one month. Without it, the full amount posts only on its due months. Existing recurring entries keep their previous behaviour (monthly, full amount).
